Cancellous.
The femur bone is composed of osseous tissue (bone tissue) which includes compact bone and spongy bone. Additionally, the femur contains blood vessels, nerves, and bone marrow.
Spongy Bone

The type of marrow that is made up primarily of fat cells is the yellow bone marrow. The red bone marrow is made up of myeloids.
The diaphysis of a long bone contains yellow bone marrow, which primarily consists of adipose (fat) cells.
yellow
No, fat is not stored in spongy bone. The majority of fat in the body is stored in adipose tissue, which is a type of connective tissue located beneath the skin and around internal organs. Spongy bone is a type of bone tissue that contains bone marrow, not fat.
Yellow marrow
Hematopoietic tissue is the tissue type associated with red bone marrow, responsible for producing blood cells such as erythrocytes (red blood cells), leukocytes (white blood cells), and platelets.
There are 2 types of bone tissue: Spongy or cancellous bone (head of most large bones, ribs, shoulder blade) and Compact (in the diaphysis or middle part of large bones). Compact bone forms the extremely hard exterior while spongy bone (also called cancellous bone) fills the hollow interior. Within the inside of the long bones is bone marrow.
